I am trying to enable and rename labels within a MySQLDataReader in C#. I am willing to do this outside of the loop if possible, but was wondering if there was a way to dynamically change the name of a variable. For example:
while (listNamesREAD.Read())
{
int i = 0;
//TextBox1.Text = TextBox1.Text + fieldnames.GetString(0) + ", ";
stringArray[i] = "List #" + listNamesREAD.GetString(0) + ": " + listNamesREAD.GetString(1);
list1Label.Text = stringArray[i];
i++;
}
If possible I would l开发者_如何转开发ike the code to be able to change the name of list1Label each time it loops through. I am relatively new to Visual C# so any help would be greatly appreciated.
using (MySqlCommand cmd0 = new MySqlCommand(listNames, conn))
{
conn.Open();
listNamesREAD = cmd0.ExecuteReader();
try
{
while (listNamesREAD.Read())
{
int i = 0;
//TextBox1.Text = TextBox1.Text + fieldnames.GetString(0) + ", ";
stringArray[i] = "List #" + listNamesREAD.GetString(0) + ": " + listNamesREAD.GetString(1);
list+i+Label.Text = stringArray[i];
i++;
}
}
I am also willing to accomplish this outside of the DataReader if possible as well. Using a normal while loop because the array size is dynamic so I know exactly how many times to loop through -- it's just a matter of dynamically changing variable names.
You will need to have an array of TextBox
es you loop through. There is no way to accomplish this how you want to as C# is a statically typed language.
You can use the Controls
property (which is a collection of all controls in the form) to accomplish what you need. You can access the controls by the indexer and the Controls' name:
this.Controls["label1"].Text = yourText;
do you want to change label name to accomplish which aim? do you have label named as: label1, label2, label3 and you'd like to change their text property?
you could do that by using linq.
